A pendulum consist of a wooden bob of mass (m) and length (l). A bullet of mass (m_{1}) is fired towardsthe pendulum with a speed \upsilon_1.The bullet emerges out of the bob with a speed {\upsilon_1}/3 , and the bob justcomplete the vertical circle. The value of \upsilon_1 is

Correct Answer is : 32(mm1)√5gl

( { m }/ { m _ { 1 } } ) \sqrt { 5 g l }

{ m }/ { m _ { 1 } } \sqrt{ { g }/ { l } }

{ 2 }/ { 3 } ( { m }/ { m _ { 1 } } ) { \sqrt { 5 g l } }

{ 3 } /{ 2 } ( { m }/ { m _ { 1 } } ) \sqrt { 5 g l }
